refactor(settings): relocate profile-path + secret-backend diagnostics into Data tab

Profile path and secret backend are **read-only diagnostic facts** —
they tell you which directory the profile lives in and which keystore
ciphertexts are stored against. They are not preferences; they do not
belong in the General tab alongside the theme / language / auto-update
controls.

Moved both into a new "Profile" group inside the Data tab, rendered
via a small `ReadOnlyRow` helper so both pieces of information share
consistent bordered-card styling and get a clear label/value split.
General tab now contains only the three actual preferences (theme,
language, updater) + the inline updater hint.

The previous General rendering dropped profile path as raw mono text
under the updater checkbox — visually tangled with the preference
control. With diagnostics in Data and preferences in General, each
tab reads with a single purpose.

No new i18n keys required — reused `exec.profile` / `exec.profilePath`
/ `exec.secretBackend`, which were already translated in zh + en.

Follow-up polish; no behavioral change. Typecheck + lint pass.
